Overview

Introducing the Cat® 789 (04) Autonomous Water Truck

An industry first, the Cat® 789 Autonomous Water Truck is a complete solution that not only automates the truck, but also automates the delivery of the water — optimizing the complete haul road watering process. Autonomous water trucks help dust suppression on site and enhance productivity by enabling mine operations to digitally track water consumption and reduce waste.

The Cat Autonomous Water Truck includes the full support of the Cat dealer and parts network. Combining an automated water delivery system with an autonomous truck, powered by MineStar, creates a truly automated solution that takes haul road watering safety and efficiency to a new level.

Benefits

Enhance Safety and Productivity at Your Mine Site

Know where and when to water – lower dust levels, increase visibility, maintain haul road safety.

Autonomous Water Delivery with Cat® MineStar™ Command

Provides consistent watering to match production targets.

Reduces Environmental Impact

Knowing precisely how much to water can help you save water.

Displaying 1-6 of 7

ENHANCED SITE SAFETY

        
  • The Cat 789 water truck is equipped with the Command for hauling autonomous haulage solution, which makes it possible for the truck to drive among other staffed and autonomous machines, along haul road routes and within active load and dump areas.
    •     
  • Enhances safety by removing operators from hazardous or remote sites and reduces the number of people required on site.
    •     
  • The Cat Water Delivery System utilizes automatic start and stop to help eliminate overwatering at road intersections.
    •     
  • The system reduces water volume as ground speed is reduced — preventing overwatering at haul road intersections, at the start of grades or when traffic is encountered.
    •     
  • It minimizes dust, uses less water and prevents underwatering or overwatering — eliminating reduced traction events and allowing water trucks to travel at higher speeds for improved efficiency.

INCREASED PRODUCTIVITY

        
  • Properly watered haul roads directly impact fleet cycle times, enabling you to meet production targets.
    •     
  • Improves efficiency, enables consistency in operations and provides near-continuous operation through the reduction of operational delays.
    •     
  • Spend less time maintaining haul roads using proper watering techniques to solve overwatering and underwatering concerns.
    •     
  • Prevent damage to trucks and reduce unplanned downtime with properly watered haul roads.
    •     
  • The autonomous water truck coordinates its speed with haul trucks to ensure it does not impede haul traffic and reduce hourly productivity.

CAT WATER DELIVERY SYSTEM

        
  • The Cat Water Delivery System (WDS) is designed to put water to the ground in a controlled, intelligent way.
    •     
  • This automated system, which is a fully integrated Cat design, controls the amount of water and spray patterns to prevent the hazards common with overwatering. The system improves safety and productivity while saving fuel and conserving water.
    •     
  • When the truck speed drops below 4.8 kph (3 mph), the system shuts off automatically to prevent overwatering, and then automatically re-starts as speed increases.
    •     
  • Pump features soft startup and shuts off automatically when the tank is empty, eliminating damage and preventing the pump from running dry.
    •     
  • Refilling process is completely automated – water truck recognizes when it’s time to refill.
    •     
  • Maintenance-free and self-cleaning water spray heads reduce truck downtime.

CAT® MINESTAR™ COMMAND

        
  • Cat MineStar Command for hauling creates a fully autonomous water truck that operates safely around other equipment, light vehicles and personnel — all without an operator on board.
    •     
  • Key to watering operations, MineStar also helps the autonomous truck maintain stability by controlling steering, braking and traction.
    •     
  • 100% compliance with watering plan and zero incidences of overwatering.
    •     
  • Water truck reports & tracks amount of water delivered with compliance to site watering plans.
    •     
  • Provides consistent watering to match production targets.
    •     
  • Technology connected to our water delivery system increases efficiency to help optimize your water truck fleet size.

SUSTAINABLE OPERATIONS

        
  • The Cat Water Delivery System provides variable water flow based on truck speed and determines appropriate flow to conserve water.
    •     
  • Know where, when, and how much to water using technology driven by automation.
    •     
  • Automated system uses less water and efficiency improvements reduce fuel usage.

MONITOR YOUR WATER OPERATIONS

        
  • The Cat autonomous water truck is equipped with Cat MineStar, which collects and communicates real-time information and provides data logging capabilities critical to minimizing safety-related liability.
    •     
  • MineStar provides information on truck location and utilization data, fuel and water level, whether or not the truck is spraying water, and WDS utilization.
    •     
  • Optional premium connectivity includes a comprehensive reporting package with data and reports that can help improve watering efficiency.
    •     
  • Water solutions data can help ensure you're meeting regulatory requirements.
    •     
  • MineStar doesn't just monitor how much water the trucks have put down. It monitors the actual saturation levels of the haul roads.
    •     
  • Watering assignments can be amended on request when it's necessary to address watering of specific haul roads or locations. For example, a water truck may be reassigned to a load or dump area to address priority dust suppression needs based on pit personnel requests.

Cat® MineStar™ Command for hauling takes advantage of the most sophisticated technologies available to deliver a next-generation haulage solution — one that boosts safety, productivity and availability on busy mine sites, especially those in difficult or remote locations. Command provides the fully integrated operation of autonomous mining systems, allowing them to haul more efficiently with near-continuous operation and move more with fewer people on site. Autonomous trucks operate safely around other equipment, light vehicles and personnel. Command trucks respond to calls to the shovel, move into position, haul to dump points and even report for maintenance — all without an operator on board.
